JP 2012-215836 A

In the layer transfer device as described in Patent Document 1, there is a demand to replace the multilayer film and a demand to prevent unnecessary heating of the multilayer film in the main housing.

However, if an opening for exchanging the multilayer film is provided in the main housing and the heating roller is configured to be movable within the main housing in order to prevent the multilayer film in the main housing from being heated unnecessarily, heat The problem is where to place the pressure roller.

Although it is conceivable to provide a pressure roller on the cover for closing the opening, in that case, it becomes difficult to transmit power from the main housing to the pressure roller.

Therefore, an object of the present disclosure is to provide a layer transfer device that can exchange a multilayer film, suppress unnecessary heating of the multilayer film, and transmit power to a pressure roller provided on a cover. be.

(1) A layer transfer device of the present disclosure includes a main housing, a cover, a pressure roller, a heating roller, a film cartridge, a motor, a first transmission gear, and a second transmission gear. The body housing has an opening. The cover is pivotable about a pivot between a closed position and an open position. The pivot shaft extends in the first direction. When the cover is in the closed position, the cover closes the opening. The opening is open when the cover is in the open position. A pressure roller is provided on the cover. A heating roller is provided within the body housing. The heating roller is movable in a second direction between a first position toward the pressure roller and a second position away from the pressure roller with the cover positioned in the closed position. The second direction intersects the first direction. The film cartridge can be loaded into the body housing through the opening with the cover in the open position. A film cartridge has a multilayer film. The multilayer film passes between the pressure roller and the heating roller in the third direction with the film cartridge installed in the main housing and the cover positioned at the closed position. The third direction intersects both the first direction and the second direction. A multilayer film has a supporting layer and a supported layer. The support layer contacts the heating roller positioned at the first position when the film cartridge is mounted in the main housing and the cover is positioned at the closed position. The supported layer has a transfer layer. The transfer layer is transferred to the sheet. The transfer layer contacts the pressure roller when the film cartridge is installed in the main housing and the cover is positioned at the closed position. The motor is provided within the body housing. The first transmission gear is provided inside the body housing. Power from the motor is transmitted to the first transmission gear. A second transmission gear is provided on the cover. The second transmission gear transmits power to the pressure roller. The second transmission gear meshes with the first transmission gear when the cover is positioned at the closed position.

When the cover is in the closed position, the first transmission gear and the second transmission gear are positioned between the heating roller and the pivot shaft of the cover.

According to such a configuration, the film cartridge having the multilayer film can be replaced with the cover positioned at the open position.

Moreover, since the heating roller can be moved to the second position away from the pressure roller while the cover is in the closed position, unnecessary heating of the multilayer film can be suppressed.

With the cover positioned at the closed position, the first transmission gear that transmits power from the motor and the second transmission gear that transmits power to the pressure roller can be engaged with each other. Power can be transmitted to the pressure roller provided on the cover.

Here, with the cover positioned at the closed position, the first transmission gear and the second transmission gear are positioned between the heating roller and the rotation shaft of the cover.

That is, the first transmission gear and the second transmission gear mesh at a position closer to the rotation shaft of the cover than the heating roller.

Therefore, even when the pressure roller receives a pressing force from the heating roller, the meshing between the first transmission gear and the second transmission gear is unlikely to be disengaged, and power can be stably transmitted to the pressure roller.

As a result, the multilayer film can be replaced, and power can be transmitted to the pressure roller provided on the cover while suppressing unnecessary heating of the multilayer film.

(2) The first transmission gear may be rotatable about a first axis extending in the first direction. The second transmission gear may be rotatable about a second axis extending in the first direction. In this case, the distance between the second axis of the second transmission gear and the rotation axis of the cover may be different from the distance between the first axis of the first transmission gear and the rotation axis of the cover.

According to such a configuration, it is possible to smoothly mesh the second transmission gear with the first transmission gear by moving the cover from the open position to the closed position.

(3) The body housing has a body side wall that is a side wall of the body housing in the first direction. The cover has a cover sidewall that is the sidewall of the cover in the first direction. In this case, the first transmission gear may be covered by the body side wall in the first direction. The second transmission gear may be covered by the cover sidewall in the first direction.

According to such a configuration, when the cover is positioned at the open position, the side wall of the main body can cover the first transmission gear, and the side wall of the cover can cover the second transmission gear.

As a result, the first transmission gear and the second transmission gear can be protected with the cover positioned at the open position.

(4) The layer transfer device may further include a sheet ejection roller. A sheet discharge roller is provided on the cover. The sheet ejection roller ejects the sheet that has passed between the pressure roller and the heating roller. In this case, the power from the motor may be transmitted to the pressure roller and also to the sheet ejection roller via the second transmission gear.

According to such a configuration, since the sheet discharge roller is provided on the cover, the sheet discharge roller moves away from the main housing together with the cover when the cover is positioned at the open position.

Therefore, the sheet ejection roller is less likely to interfere with replacement of the film cartridge.

Also, the power transmitted to the pressure roller can be used to drive the sheet discharge roller.

(5) The sheet discharge roller may be positioned on the opposite side of the cover rotation shaft with respect to the pressure roller.

(6) The number of gears that transmit power from the motor to the pressure roller may be less than the number of gears that transmit power from the motor to the sheet discharge roller.

According to such a configuration, power can be transmitted to the pressure roller, which requires torque, using fewer gears than the sheet discharge roller.

As a result, the pressure roller can be stably rotated.

(7) The film cartridge may comprise a supply reel and a take-up reel. A supply reel is wound with a multilayer film. A take-up reel winds up the support layer of the multilayer film. The layer transfer device may comprise a transport roller, a first gear train, a second gear train, a third gear train, a fourth gear train, and a fifth gear train. The transport roller transports the sheet toward the pressure roller. The transport roller extends in the first direction. The first gear train is provided inside the body housing. The first gear train has a first transmission gear. Power is transmitted from the motor to the first gear train. A second gear train is provided on the cover. The second gear train has a second transmission gear. A second gear train transmits power from the first gear train to the pressure roller. The second gear train has a clutch. A third gear train is provided on the cover. The third gear train connects with the second gear train. The third gear train has a first transport roller gear. The first transport roller gear is attached to one end of the transport roller in the first direction. The first transport roller gear is rotatable together with the transport roller. The fourth gear train is provided on the body housing. The fourth gear train connects with the first gear train. A fourth gear train transmits power from the first gear train to the take-up reel. A fifth gear train is provided on the cover. A fifth gear train transmits power to the sheet ejection roller. The fifth gear train has a second transport roller gear. The second transport roller gear is attached to the other end of the transport roller in the first direction. The second transport roller gear is rotatable together with the transport roller.

According to such a configuration, the take-up reel and the pressure roller of the film cartridge can be driven by a common motor, and the pressure roller is rotated independently of the rotation of the take-up reel by the clutch. can be made

Further, power can be transmitted in the first direction from the second gear train to the fifth gear train using the transport roller.

Therefore, the fifth gear train that transmits the power to the sheet discharge roller can be arranged apart from the second gear train having the clutch in the first direction, thereby suppressing an increase in size of the layer transfer device.

According to the layer transfer device of the present disclosure, the multilayer film can be replaced, and power can be transmitted to the pressure roller provided on the cover while suppressing unnecessary heating of the multilayer film.
